| 1 | | This problem is now resolved on my system with build build 4.3.26 r98988. I'm running a Win7 x64 SP1 host on an HP dv7-4283cl laptop with 8Gb memory and switchable AMD/HP graphics. XP and Win7 x64 VM guests are running flawlessly. I have not tested it with other OS VMs. |
| | 1 | On my system if the following files are patched by the Windows 7 universal theme patcher), this consistently generates the "Unable to load R3 module" problem even when the v4.3.26 r98988 host is installed: |
| | 2 | |
| | 3 | themeservice.dll |
| | 4 | themeui.dll |
| | 5 | uxtheme.dll |
| | 6 | |
| | 7 | Generally, you can ensure that these files are not patched or corrupted by running the following at the command prompt: |
| | 8 | sfc /scannow. |

| | 10 | The universal theme patcher is used to enable third party themes in Windows 7. Installing the UXTheme Multi-Patcher v14.2 enables third party themes by patching the files "in memory" yet leaving them untouched as files. When this is installed, I can successfully install and run all Windows hosts in Virtual Box. |
