Hi Timothy, welcome to the
Lumion Support Forum.
This issue is most likely easily resolved.
Please try this:
1. Control Panel > Programs & Features (add/remove programs) > first look for Microsoft Visual C ++ 2012 x64 > right click > change (not remove/uninstall).
2. A window will pop up > choose repair.
3. The Microsoft Visual C ++ 2012 x64 will be repaired > finish
4. Then look for Microsoft Visual C ++ 2012 x86 > right click > change (not remove/uninstall).
5. A window will pop up > choose repair.
6. The Microsoft Visual C ++ 2012 x86 will be repaired > when finished it will ask for a reboot/restart.
7. You should also try same steps for any other Microsoft Visual C ++ versions and for both x64 and x86.
