Guest Michael Q Posted August 10, 2008 Posted August 10, 2008 I have been trying to install SP3 on my Windows XP PC. Each time I try I get the following error:- drwtsn32.exe - Application error. The instruction at "0x5780e1c0" referenced memory at "0xddc20074". The memory could not be read. The only way to get out of the problem is to manually turn the machine off and restart.
