Uninstallation problem on W2000

[SV0001]

Hello,

I have a problem of uninstallation on Windows 2000. When I click on add/remove programs and choose my application (installed with v5.5.1) nothing is uninstalled except uninstall log that is removed. So I cannot try it again.

Does anybody encounter this problem ?

I am having a similar problem. When I add/remove my program my custom dll finishes executing no problem. Then control passes back to IsUninst.exe. At that point something goes hay wire and nothing gets removed except for the uninst.isu file.

I've tried adding -m to the IsUninst.exe call to examine the .mif file that gets created during the uninstallation process. I can't understand from looking at this file what happened but there is at least some indication that uninstallation process failed.

An interesting point here is this: If I don't run my custom uninst.dll code then the uninstaller runs fine. Given that, I've narrowed the problem down to a DeletePort() call that removes a port associated with a custom printer we added during installation.

I'd sure like to get my hands on a debug version of IsUninst.exe. I'm sure this is impossible. Anyway - I need help on this one.

Thanks
Rob
