View Full Version : Error while building a patch for an InstallShield Basic MSI Project

08-22-2005, 02:01 AM

I tried to build a patch for an InstallShield Basic MSI Project. Therefor I created a Quick Patch Project to replace some of the files in the target INSTALLDIR. Unfortunately I receive always the error -6520, which I cannot get rid of. I have tried nearly all, which I could find in the internet help of InstallShield concerning this error, but nothing helps. :(

Could someone tell me, what I do wrong?

Thanks a lot ...

By the way: There is also the possibility to create a patch within a Basic MSI Project - but I do not understand the difference between a "previous setup" and the "latest setup". I guess that in my case it's identical.

I use InstallShield 11 Premier Edition.

Thanky you for all replies ...

6520 is com related error. I think you must be updating some self-register files, you may need to clean the registry before you update file.
