When running TDCI’s BuyDesign Design Studio version 8.0 you select the appropriate instance and application, then receive the error message shown below.
Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
‘.’, hexadecimal value 0x00, is an invalid character, Line 1, position 1.
To solve this problem we’ve deleted the DesignStudio subfolder located in C:\Users\%username%\AppData\Roaming\TDCI\.
Next time the application is started this folder will be recreated. After doing this we were able to start the Design Studio application successfully.
