Diablo 3: Could Not Install Invalid Installation Options Error

Are you installing Diablo 3 in your PC but you encountered the error – “Could not install. Invalid installation options. Please try again? We’ll tell you how to resolve this.

Considering the demand of Diablo 3, I was lucky to be able to buy a copy only after a few days after its launch. Having played the 2 previous Diablo games, I was really looking forward in playing this one. However, when I was trying to install Diablo 3 in my PC, right after agreeing to the terms and conditions, this was what I got:

Not much of a choice right? I clicked ok and just like that, the installer exits. I tried to re-install and double click the setup files in the DVD installation disc several times but the error still appears. I even tried the options menu in the installer but it doesn’t help in resolving the error encountered above.

 

Solving the Could not Install. Invalid Installation options Error

Remember when you first installed Diablo 3 and it downloaded and updated some of the setup files? Well sometimes, something goes wrong in this process and not all necessary files are downloaded correctly.

To resolve this, just go to C:\ProgramData\Battle.net\Setup\diablo3_ensg\ folder and then delete the file Diablo III Setup.exe

If your hard drive letter is not C: then just change it to the appropriate hard disk letter (i.e. D:\ )

If you installed Diablo 3 in Windows XP, try looking for Diablo III Setup.exe in C:\Documents and Settings\All Users\Application Data\Battle.net\Setup\diablo3_ensg\ folder. If you still can’t find it, try the Search function in Windows.

 

Once you’ve deleted Diablo III Setup.exe, you’ve now solved the Could not Install. Invalid Installation options Error. Just re-run the installation and then your installer would again try to update.

      I don’t think you need to reformat you’re PC. I suggest that you make sure first that you have done all the steps detailed here. Make sure you have an active internet connection as well and you’re firewall is not blocking Diablo 3 in any way.

      If all else fails, you can always do a re-install of Diablo 3.
