This is happening to Windows 7 professional 64-bit PC but Steam works fine on my non-gaming laptop. If you open your Windows task manager while Steam is running, go to processes and find steam.exe, the description for it is now 'Steam Client Bootstrapper,' with the builtbot, etc stuff in parentheses. Both solution have failed to produce any results. Steam Client Bootstrapper Has Stopped Working Solved Driver Easy. Apparently it's the new description for the steam.exe file. steam client bootstrapper has stopped working windows 7 This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10, Windows 8/8.1, Windows 7 operating systems.Works for all major computer manufactures (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung). Namely, the solution to rename the Clientregistryblob file, and restart steam and the solution to delete everything in the steam folder except for steamapps and steam.exe and then rerun the program. Now, I tried using Google and searching the steam forums for help and I tried the solutions that were posted. So I decided to restart Steam, unfortunately when I tried to sign in, at the 'Connecting Steam account.' popup, the game would give me the error seen above. When I would try to play the game Steam wouldn't do anything ( as if I never clicked the play button). However, yesterday I had just gotten the Rising Storm Beta Access from a friend and installed it. The first time it happened was the day before yesterday, luckily it resolved itself after I exited Steam for awhile. Hey all, I've been having trouble logging into Steam since yesterday.
