This question was at least partly asked before but it didn't receive any reply. So, I also have problem when installing Borland C++ Builder mobile edition. I install all the modules (SDK, mobile plugin, C++ Builder). When I then start the Builder it cannot find the SDK - I get error: "No SDK detected. A valid SDK has to be installed". On installing phase SDK gets there just fine. It is installed, path and EPOCROOT are set to correct places but Builder just don't see that. If I check from Builder's Tools -> Mobile Options I can also see that path and EPOCROOT are on place but there's no installed SDK and I cannot even add SDK from here!?! What should be done to get Builder to notice the SDK?
