When I try to install Microsoft SQL 2008 R2, I get the following error durring install:

Any ideas why SQL server is failing to install?

Windows 7 Ultimate 64bit, Intel x64 CPU, 4GB ram.

If I'm not mistaken, activeds.dll is a normal part of Windows that the installer is expecting to be present, not something that gets installed with SQL Server.

I would suggest running sfc /scannow to repair missing/damaged system files.

p.s. it might not be a bad time for an anti-malware scan. ESET and VIPRE both come recommended, and both have fully functional time-limited trial versions. I do not recommend Symantec or CA antivirus.

"Activeds.dll errors are caused by situations that lead to the removal or corruption of the activeds DLL file.

In some cases, activeds.dll errors could indicate a registry problem, a virus or malware issue or even a hardware failure."

Miles mentioned many of the possible solutions to the error, more details & possible fixes are available here:
