Hi All,

I have created a msi for my application.
While testing, I observed below issue:

While installation, if installation folder is already exist and some files of my application are also exist in installation folder. Then msi unable to replace some files out of those which are already in installation folder.

I also tried by running msi with logs on. But, there is no error occurred in msi logs file.
In msi log, msi performs "ProcessComponents" action, but "InstallFiles" action does not execute for those file.

If any one have idea about it, please let me know.
Waiting for your reply.

The files which are not being replaced are most likely files without version information e.g. TXT or HLP files, something like that?

Look up on MSDN's Windows Installer section about non-versioned files. In essence you need to set the component containing the file(s) to always overwrite existing files.

BTW, this forum is designed for use in deciphering errors returned by the Windows Installer engine. To see examples, click the 'MSI Errors' link at the top of the page. You should have posted in the 'package Development' forum. A moderator may well move the thread.
