minor upgrade question
I have a question regarding a minor upgrade
I need to upgrade 4 files in a package. LEts call them temp1.txt,temp2.txt,temp3.txt and temp4.txt
The files does not contain any version number
File 1-3 is upgraded fine because they are larger than previous version, but number 4 is not upgraded because its identical as previous version(in size)
What would you say is the best way to get this file replaced wit the new one

Since they're not versioned files, use the RemoveFile table to, er, remove them first.

Thx mate it works perfectly[:D]
I had never used this table before i guess the only thing i have to consider is that removfiles is executed before installfiles. Correct?

Correct. A glance at the sequence tables would have confirmed that. :)

Instead of using the RemoveFile action, you can simply add a version value to the file table - even if the files in question aren't versioned.
This will ensure the new file overwrites the existing nonversioned file. According to the Windows Installer File Versioning Rules in the MSDN library:
"Versioned Files Win—A versioned file gets installed over a nonversioned file"

Why bother, though? Straight away you're into a maintenance headache, in keeping track of which version number was assigned to which file.

I totatally agree with VBScab. Doing so will result in more maintenance in the future-but thx for the answer greenmagnet
