DirectX Not Recognised - PC Version - Win 7

[Raist]

oops... forgot this tidbit wen I posted earlier. Have you enabled .Net 3.5? Those installers might make some calls that were deprecated in 4.x. Enabling the 3.5 framework should workaround that. It's under the programs/features snap-in, Turn Windows Features on/off (can just run appwiz.cpl instead of drilling through control panel). Users of 8.1 that may be looking for this also, I think it's under a sub category for Legacy components or something like that.

you could start by posting the contents of those logs from the windows folder.

Just to rule it out...did you right-click and run them as admin?

Yes, I've tried running as admin, still the same error pops up.

This seems to be system corruption of some kind, involving the windows catalog storage. . . .

[Fenririon]

SYSTEM_OS Windows 7 Ultimate 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_rtm.101119-1850)

RTM? Is that even supported anymore?

[Squa11_Leonhart]

RTM? Is that even supported anymore?

RTM is in all windows release buildstrings, all it means is Release to manufacturing (RTM)

[Fenririon]

My bad! Confused it with RC.

[Vohs]

Was there ever any workaround for this?? I seem to be having the same problem

[Karl-Pilkington]

I've managed to solve the issue, but not the way I would have liked.

I ended up buying a copy of Windows 8.1 64-bit and upgrading to that.

This then allowed me to run the DirectX End-User Runtime web installer and run the updates.

I then needed to upgrade my graphics drivers to be compatible with 8.1, then I've been able to play ever since.

I guess I'll never really figure out why I couldn't fix this on Win 7

[Squa11_Leonhart]

As i said, it sounded like catalog root store corruption, this would cause all files that were digitally signed within a certain date range to appear corrupted and unable to be installed properly.

a reinstall of win7 would likely have resolved it.

but not worry, you'll have a free upgrade to windows 10 once its out.
