Visual Studio 2010 fails with the following error:
Product: Microsoft Visual Studio 2010 Express Prerequisites x64 – ENU — Error 1719.The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance.
We could to do the following steps to fix the issue:
When the value of the WOW64 is set to 1 application would see the OS as 32 bit. This is helpful in running installer packages that are not compatible with 64bit OS. However, most of the 32bit installers are compatible with 64bit OS and do not need this value to 1. When the value of WOW64 is set 0 it returns the actual OS architecture to the installer. That is if it is 32 bit then the installer will come to know it’s a 32 bit OS, similarly it’s true for 64bit OS.
