I have installed Vampire the Masquerade: Bloodlines, via Steam, on my 64-bit Windows 7 machine.

I found this question: "Available memory less than 15MB" error when launching Vampire: The Masquerade - Bloodlines

I followed most of these instructions, and the game runs great! The "memory bug" patch ran without a problem. The "resolution patcher" ran without a problem. I set the executable to run in compatibility mode so the opening animations are visible. Still no problems...

However, I would like to try installing the unofficial patches. I downloaded patch 8.1 from here: http://www.patches-scrolls.de/vampire_bloodlines.php

When I try to execute VTMBup81b.exe, I get a popup window that says:

The version of this file is not compatible with the version of Windows you're
running. Check your computer's system information to see whether you need an
x86 (32-bit) or x64 (64-bit) version of the program, and then contact the
software publisher.

Then, I tried to be clever. I copied the directory where Bloodlines was installed onto a 32-bit Windows XP Virtual Machine. I copied the patch there. When I tried to execute the patch file under the XP VM, I simply got "Cannot execute VTMBup81b.exe" (on the command line, not a Windows popup).

I tried the same thing with the version 7.9 patch, just to be sure, and I got the same results.

How can I get this patch to install?

  • Try changing the compability mode on the patch itself.

  • Tried that, it doesn't change anything.

  • Did you check if you aren't missing any DLLs with Dependency Walker or similar? Aug 20, 2012 at 9:08

Well.. it turns out that somehow there was an issue downloading the patches -- both the 8.1 and 7.9 -- in the first place. They were each 41k in size. On a whim, I tried re-downloading, and the 8.1 patch was over 200MB this time (!).

After re-downloading and getting the 200MB version, the patch installer started up fine.

Really not sure what happened here. But I'm all set now.
