Installation Errors: OS Not Compatible(1)Category: Technical SupportJuly-19-2013 4:53 PM PDT (9 years ago) Go to Blizzard forum post
I've just brought back to life my older gaming rig for a roommate who is trying to install D3. The OS is currently running on Window's Vista Home Premium. However, when starting the Installer, it keeps denying us with a message that says, "This OS is not compatible with D3, we can not install D3."

Checking over the minimum requirements for D3, there should be no problem with D3 on Windows Vista. What seems to be causing thing problem? Has anyone else had the same issue and worked it out?

Gromskull,

Make sure you've updated your Windows Vista to Service Pack 2.

Gromskull,

Can you post some information about your computer? You can find this information in the Direct X Diagnostic Tool:

Click on Start
Click on Run
Type in: dxdiag (In Vista, type dxdiag in the search field)
Hit Enter or OK

Click on the Save All Information button at the bottom, and create a dxdiag text file, and copy and paste it ALL here.

Gromskull,

It's a very common issue and I'm pretty sure this is going to resolve it for you.
