Solution to Rocksmith Crashing on Startup:
How to Fix the White Screen / "Rocksmith.exe has stopped working" Error
Rocksmith not opening or crashing during startup seems to be a fairly common issue among both retail users and people using the TiNYiSO crack.
My game would run for a few seconds on a black screen with an amp tube in the bottom right before crashing with the "Rocksmith.exe has stopped working" error message from Windows.
This issue occurs while using "Rocksmith.exe" and the No-Cable Fix "RocksmithNoCableNew.exe" (Download here: http://adf.ly/79388/rocksmithnocablenew)
Some popular solutions that didn't work for me:
➥ Running rocksmith.exe as an administrator
➥ Running rocksmith.exe in Windows XP SP3 Compatibility Mode
➥ Adding the Rocksmith game directory as an exception in your anti-virus software
➥ Opting out of the latest Steam betas
A not-so-popular solution that worked for me:
Download and install DirectX End-User Runtimes (June 2010):
