visual studio .net setup: Has anyone successfully set a file condition?

I include an MDB in our installation. Upgrade installations may overwrite
previous versions. I'm using the following in the Condition property of the
MDB file: ProductVersion < 1.0.9. That alone, and a change of the version in
the Project Properties, has no affect on the installation. The file gets
overwritten every time, unless I set the MDB's Permanent property to True and
then it NEVER gets overwritten. ProductVersion < 1.0.0 has no affect on the
installation.

Any thoughts?

Hi,

Thank you posting!

Based on my understanding, the problem is the ProductVersion's evaluation
does not work in your VS setup project's launch condition.

If so, since the ProductVersion's value is not a number, I suggest you add
the double quote mark around the specific value, for example:

ProductVersion<"1.0.9"


Thanks!

Best regards,
