Trouble linking target with debug information

Hello,

today I first time tried to compile 32 bit target with debug symbols and got strange error:

Code:

---

LINK : fatal error LNK1101: incorrect MSPDB100.DLL version; recheck installation of this product

---

I think I have the most recent VS 2010 build (updated regularly via WU) then don't understand why the linker is complaining. Having properties of LINK.EXE and MSPDB100.DLL I got this verinfo:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Vc\LINK.EXE:
10.0.40219.01
MD5: 60f3d6c30c1bbfb4da62df454a4be470

C:\WINDOWS\SysWow64\MSPDB100.DLL:
10.0.30319.01
MD5: 609c1d1be515d18aa64e3a6b571d5ba7

Perhaps some installed product replaced the DLL with it's own MSPDB100 version?
I don't know where to get MSPDB100.DLL that will work with my VS linker.
Anybody could help?
