Hey ,
thank you for your response. I should have been more specific.
I use the launcher binary (4.7.6) and the error occurs if I try to debug the project, just by pressing Start Debug F5 (I attached the error message). Everything else works fine, so building the project within VS and Compiling from the editor works fine. I work with Win7 64 Bit and MS VS Community 2013 Version 12.0.31101.00 Update 4.
I had some trouble with starting UE4 and therefore I uninstalled UE4.7.5 and the Launcher over the normal Uninstall Windows GUI. Additionally I removed all remaining folders which belonged to UE and Epic Launcher. I think the folder C:\Program Files\Epic Games remained after the installation, so I deleted the whole folder manually.
It could be that I had VS open during the uninstallation or afterwards and there were some dependencies VS couldn’t find because UE wasn’t installed anymore. Could it be that UE normally creates a symlink called UE4.exe in the folder VS can’t find, which links to UE4Editor.exe?
This error still occurs even after the update yesterday from 4.7.5 to 4.7.6
