Is to use the app compatibility in the app's shortcut and set it to XP or Vista.
And with 200 customers why not call and pay Microsoft for their thoughts?
And why not let the developer look at it?
I have some old VB6 app and it's running fine on 7 (32 and 64 bit) but I had to alter the install a little. Not the VB6 install but the MySQL component.
before you point me to other threads I have to say I read them all in last days
This is MY problem:
there is this huge vb6 app that worked fine on XP, now when run on win 7 on half PCs is working on the other half it just does not.
If I install vb6 on the pc that the app is not working it will work fine after.
But I cannot install vb6 and should not install it on all those that it does not work, could be more than 200 installations.
I uninstalled vb6 and tried to check which dlls or ocxs are needed, I copied those from:
into system32 and syswow64 but still no luck.
I wanted to install vb6 service pack 6 but could not installed it successfully,
I could install vbrun60sp6.exe, the vb6 runtime, but it was not enough, the app is not working.
