Many people have told us that they have encountered a certain little "run time error 429" and "ActiveX component can't create object" while trying to install or play Cowtris 2.0. David is investigating and dealing with this evil little bug right now (well, not actually right now, but you get the idea), but here is a fix that may work:

Go to Start, Run, and enter: regsvr32 ssubtmr6.dll
Then go to Start, Run, and put in: regsvr32 ccrptmr6.dll
