I have 2 computers, both are Win XP, both previously had MC12 installed.
I purchased MC15, and upgraded it in PC1.
I then did the Portable install onto my player (Sansa View in MSC mode).
I verified that I could run Media Center 15.exe from the portable drive letter on PC1, and it worked fine.
Next I plugged the player into PC2 (which has MC12 installed still).
If I try to run Media Center 15.exe, I get an error message saying it can't load MCTools.dll.
Using SysInternals Process Monitor, it looks like MC15 is reading and loading MC12's MCTools.dll on startup, instead of the one in its local directory.
I then uninstalled MC12 from PC2.
Now when I run Media Center 15.exe from my portable device, I get the error message: "Media Center was not installed correctly for the current user. Please Reinstall Media Center".
Any thoughts as to how to resolve this?
Side-note, I also had a portable install of MC12 on a different portable device, and it did seem to work fine on the same 2 PCs, but I did have MC12 installed on both those machines too.
Thanks for any help!
