i have found a solution to the msvcr80.dll error. these are the steps i took to fix it.
download and run Revo Uninstaller
when uninstalling Reader, choose the advanced option, let it uninstall, then tick the boxes it finds for the reg entries. this will remove all the registry leftovers.
delete the adobe folder
go to http://get.adobe.com/uk/reader/otherversions/ and select the correct operating system (and SP) and your country.
download and install.
with any luck, it should now work.
this worked for me, good luck
