From a windows 7 x64 machine when I try executing the following:
vncviewer.exe a.myvnc.com:8888 /dsmplugin SecureVNCPlugin.dsm
using the 64-bit viewer I get an error of:
"The Plugin cannot be loaded
Please check its name integrity"
I tried a different plugin and I get the same error but it will work fine if there is no plugin used.
I used the 32-bit viewer it seems to work perfect with the plugin in the command. Does the 64-bit require a different formatting of the plugin for command line use?
