If i install Visual Web Dev 2K5 express or VC# 2K5 Express while having VS 2K8 TS, would they crash?

hi,
I use VS 2K8 TS (without SP1) thus .NEt frame 3.5 is also witout SP1. I have a problem with my VS 2K8 TS that i cannot Drag and drop controls on to the web forms.... i was told to run certain file on WCU in the VSTS DVD... yes i could do that...but at momment i dont want to do this beucase i need to extract the ISO..whichtakes some time... so i was wondering is this problem occured becuase of not having SP1?
If i need to DL SP1 i cannto do this sstright away due to my broken router...atm using Dialup.... so i thought that since i have Express versions of VS 2005, that i should install either VC# or Visual web developer. If i install VC# 2K5 Express or Visual Web Developer 2K5 Express while having VS 2K8 TS installed in the system would they crash?
TY
