I am unable to get the new viewer to complete its instalation, it seems to be a scripting error about 3/4 of the way through and I have to abort....help I am running winows 7 and during installation i get... "Error for opening file for writing" during the instalation, whereby I have to click the abort popup and then get "cant write c:\programfileas\secondlifeviewer\zlib1.dll" I have never had any problems installing new v2 updates before
