update old sc (online creator) update 27/08
Re: update old sc (online creator) update 27/08
Good day everyone.
I too am now having to change from several years of UVNC SC under XP to having to support Vista and Windows 7,
I have read through this thread a few times now. I see where progress has been made but it seems like most of the remarks in this thread are for those who are more familiar with the workings of SC.
So here are a few questions, that if answered, I'm sure will help others. Your kind response will be most appreciated by many of us, as is your hard work in making this project work with Vista and 7.
In the original SC, we started with "Custom.Zip" which can be found here: http://www.uvnc.com/custom.zip and this is per the SC instructions found here: http://www.uvnc.com/addons/singleclick.html
Do we still start with this base? I think AERO_disable.exe is needed for Vista and Win7, but it is no in the custom.zip, nor is it inserted by the compiler at http://support1.uvnc.com/cgi-bin/upload4.pl
Can the Custom.zip be updated to handle Vista and 7?
Next, are there compatibility issues between UVNC version with SC?
I have an SC I am working with, but the latest build of UVNC 1.0.8.2 seems to crash when my SC connects to it. The WinVNC.exe that the SC tool puts in the executable is dated Aug/26/2009, is this right?
I have some more questions that I think are relevent to noobies, but they are related to configuration, I thought I'd stick to just getting it to work for now.
Is there a new how to for the SC that works with Vista and 7?
Sincerely,
Jason

Re: update old sc (online creator) update 27/08
Does anyone have this working with the display driver or dual monitors? I'm not seeing any ability to handle that. Is this feature in the Vista/7 specialized SC creator?
When I press the button to switch monitors, it works going from one to the other but when I toggle it the 2nd or 3rd time for both monitors, it crashes on me.
When I double click on the uvnc icon we use and look at the information for the connected computer, I see no box indicated whether or not the uvnc display divers are being used or not.

Win7 messag: This program might not have installed correctly
Hello all. I've spent the last 3 days learning UVNC and SC and have it working perfect! Thank you so much for this tool! Part of that time was spent using SC Builder 2009, until I realized it wasn't working well (slow) with my Win7 64bit PC on the server side. Nice tool, but SC seems to work better for me.
The rest of my time was understanding the brief doc on this site, and whether certain things applied or not. (not complaining)
The [DIS_UAC] option is a miracle!
My only question please, which I couldn't find an answer to, is how to prevent the popup message from Win7 after SC closes, which says: "This program might not have installed correctly". It's not a big deal. But the person on the server end can get alarmed by it.
Again, thanks for an awesome, awesome job everyone!

Re: update old sc (online creator) update 27/08
Hi Rudi,
I am working on Windows 2008 server and connecting to my client systems which are XP systems. I got the single-click from the below mentioned link and it worked fine(used latest VNC viewer 1.0.8.2):
http://support1.uvnc.com/cgi-bin/upload4.pl
I would like to make some branding changes to WinVNC.exe(Exe that exists in Singleclick). Can you please provide the link to source code for that.
Thanks in Advance

Re: update old sc (online creator) update 27/08
Rudi,
Just out of interest re the UAC / Administrator permissions issue - have you tried embedding a Windows Vista+ manifest file into the main vnc.exe inside the package (as well as the package itself).
This should prompt the user for elevation as soon as they run the main package and then run the whole thing with elevated permissions without the need to disable UAC manually via the reg...
You'd need to use the MT.exe tool from microsoft to embed the manifest.
Example manifest:-
(Save as e.g.: winvnc.exe.manifest)
Example MT.exe command line usage:-
Each "code" section should be on its own, single line - just remember to change the exe names 
This should mean that on 2000/XP etc it runs as normal, but on Vista/Win7/Server2008 etc it prompts for elevation first.
Just a thought (I had to do something similar elsewhere).
I'll probably try this myself as i've got to customise the ui slightly anyway.
James.
EDIT: P.s. this will fix the "The application failed to install" type prompt on vista+ machines too

Re: update old sc (online creator) update 27/08
Rudi,
Further to my previous post.
On further inspection, i'm not sure requesting Admin permissions in the manifest is a great idea (e.g. if the user doesn't HAVE permission you're stuck). Besides your [DIS_UAC] option works great anyway!
However I do still think that you need to add the compatibility bits into your manifest.
i.e.
This bit prevents the horrible windows doesn't think your software installed correctly messages 
(Should be added somewhere between the <assembly> tags)
P.s. Thanks for the update, wish i'd noticed it sooner!
EDIT: Trying to get rid of extra spacing that phpbb has added!
EDIT2: Didn't work!

Re: update old sc (online creator) update 27/08
Hello, I am trying to use the 2009 update of SC to do remote support for my customers. I have added the part in the helpdesk.txt to disable uac. I am having problems with a bug however. Whenever I open a web browser IE, Firefox, Chrome .... on the clients pc it seems that randomly the vnc will lockup (sometimes as soon as the browser is opened). On windows7 and vista i can usually have the client close the browser and i regain control. On xp machines it usually either disconnects me eventually after this happens or i have to manually disconnect because there is no regaining control. On xp machines with previous SC Versions i never had this problem, and on win7 and vista machines the old sc versions would just lockup immediately, so the new version has improved with 7 and vista but it seems to have made it so i cant help people on the internet. Is there a workaround? Am I missing something? Thank you all 
Re: update old sc (online creator) update 27/08
Sorry I don't know. Some of us have moved on to other single-click "wrapper" projects including SCPrompt and ChunkVNC. (Both are in these forums.)

Re: update old sc (online creator) update 27/08
Hi,
This didn't work for us in trying to resolve the slow refresh when listening from an XP to a windows 7 host. The only way we could resolve the long refresh delay was to create a self installer of the latest driver files that detected the version of windows and if it was 32 bit or 64 bit so as to install the correct driver. If sc was run straight after the driver install there would still be problems, not sure if that was due to the delay of the silent install or that a log off and login again was required but that is what we usually recommended to resolve it. Once the driver was installed we had no further problems with SC using either creators.

Re: update old sc (online creator) update 27/08
any chance or benefits from you all bundling the newer versions of the dlls & exe files?
What are you all using to convert zip to exe in case we want to try bundling them ourselves?

Re: update old sc (online creator) update 27/08
sc use 7zip for compression
If 7zip is installed you can extract the sfx and recompose it yourself.

Re: update old sc (online creator) update 27/08
how do you recompose it after you've made your changes?
Re: update old sc (online creator) update 27/08
Download SCPrompt and use the scprompt_builder.exe or the various batch files that are available ... that gives you options for 7zip, iexpress or now NSIS ...jawz101 wrote:What are you all using to convert zip to exe in case we want to try bundling them ourselves?
i will publish the builder as a seperate project soon, as i think others may find it useful for lots of things
You can just re-use the website again ... or use the above mentioned packages ...jawz101 wrote:how do you recompose it after you've made your changes?

Re: update old sc (online creator) update 27/08
Just tried it and it works great! However I notice that when you exit the program, the user gets a "This program might not have installed Correctly" pop up. Is there any way to get rid of this from popping up every time you close the vnc session?

Hi there, is this what is keeping me from using UVNC SC on the windows side and Remmina on a linux machine? If so, is there any possible way to get the two working together?

Hi there,
I keep trying the uploader at http://support1.uvnc.com/cgi-bin/upload4.pl but it doesn't seem to be using my custom.zip. I appear to be getting someone else's executable.
Does this uploader still work?
Thanks!

Hello there.
I am now making the switch from an earlier windows XP implementation to a windows 7, and have finally taken the inevitable. I would have to say that the upgrade in straight-line connection speed is just nice and what a big improvement at that.
I am looking at some issues though with portability of the Custom.zip file to be accessible on the windows 7.
