==i_view32.exe File Sizes==

Irfanview 3.99 didn't bump the version number in the executable, so for some versions of Irvanview (possibly not the most recent versions), when checking for which version is installed you should check the size of i_view32.exe too. The file sizes for some versions are:

* 4.25: 481792

* 4.27: 494080
