Set WOW – 32 bit .net application on a 64 bit PC

My development computer at work was a x86 PC that has windows XP. Recently I had to upgrade to a windows 7 64 bit PC which brought a lot of trouble. One among them is running a .net 32 bit application. After a lot of research I found a way to enable WOW (Windows On Windows). This is quite old and most of the techies knows about it, but I thought its worth to share it.

Here you go…
1. Open command prompt.
2. Navigate to ‘C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\’.
3. Type ‘Ldr64.exe SetWow’ and hit enter.

This will enable 32 bit CLR applications to run properly. You can always revert the settings with the command ‘Ldr64.exe Set64’.

Happy Coding!
