I am getting following error on VC2010-SP1 Win7 32-bit. I tried for HotFix but it is no longer available here https://support.microsoft.com/en-us/kb/982517. Can anyone help? Thanks

It's still available, but listed as requiring a support call (as many KBs do by default). You can however ask for a download link by email.
Since you run SP1 of VS2010, KB 982517 points to KB 2545588 for the fix. Following How can you download a hotfix without contacting Microsoft? which still works nowadays, click...
http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2545588&kbln=en-us
...accept the terms, and provide a valid email where you'll receive the download link. Be prepared for a massive download to the tune of 270+ MB. If the hotfix doesn't fix it, or breaks anything else, don't expect much support from MS (since you just agreed to their terms in a previous step ;-)).
