Reading current installed version of an application using windows api

Question

I was trying to use windows api to find out the version info of an installed application.

I used the upgrade code to find out the product code using MsiEnumRelatedProduc

Answer 1

In response to @JoshHetland the string to pass is the CamelCase postfix of the INSTALLPROPERTY_VERSIONSTRING - remember that MSI is case sensitive.

So:

INSTALLPROPERTY_VERSIONSTRING becomes VersionString

INSTALLPROPERTY_INSTALLDATE becomes InstallDate

and so on.

Complete list of properties available is on the MSDN page for the MsiGetProductInfo function .
