Hi,
I had got the same problem, I uninstal visilogic with revoUninstaller (clean folders and register)
Tweaking windows repair help to.
But, for crash of visilogic when you try to open .vlp from visilogic, I do this :
We use Visilogic on a NON admin session for basic security.
I have find the solution, but if you use admin session, it would be easier.
Start → search → redegit → go to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vlp\OpenWithList
The value are :
(default) REG_SZ (non defined)
a REG_SZ VisiLogic.exe
MRUList REG_SZ a
and Start → search → redegit → open with admin → HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vlp\OpenWithList (default) REG_SZ (non defined)
delete others values
For both :
OpenWithProgids
(default) REG_SZ (non defined)
.vlp REG_NONE (binary...)
Delete the orthers folders if the exists (like "userchoice")
Restart
Have a good day ;-)
