Hello Georges,
The error (“Lc.exe” exited with code -1) is caused by the license compiler.
In order to solve the problem it is usually enough if you delete the license.licx file in the Properties of your project.
However, I tried with Windows 8.1 and VS2013 and with C1Studio for Winforms 2013v3 and Spread 7v2 installers but I was not able to reproduce the LC.exe error. Could you please let me know any steps to reproduce this with some controls. Also, please test with the latest versions of installers for both C1Studio for Winforms and Spread and let me know if the issue still persists :
Dom,
The utility was made available in 2008-9 because there were VisualStudio IDE bugs in VS2008.
However, I will forward this request to the concerned team for consideration. Thanks for suggesting this.
Regards,
Richa
