I am getting this error after trying to upgrade 2005 to 2008R.
It failed because it wanted for me to remove 2005 tools and when I cancelled it removed some tools, but I do not what tools it removed.
I think this has to do with 2008R not been tested properly.
2008R cannot work with 2005!
I tried then to remove 2008R (well the bits it installed), it seemed to uininstall properly but it is still there! I just cannot get rid of it!
I can link to my hosting company server where from I can create and design my tables but cannot use my own!
I will call Microsoft tomorrow morning, but I guess tech support will not know what to do.... as usual...
Microsoft used to be one of the best company for supporting developers but in the last 5 years the client care has dropped dramatically.
