Signtool requires CAPICOM version 2.1.0.1 or higher

Posted on August 13, 2010 by spgennard

Just a quick blog to document a bit of pain I hit with CAPICOM and SIGNTOOL..

I got the following error:

EXEC : SignTool error : Signtool requires CAPICOM version 2.1.0.1 or higher. Please

The solution is to download and install:

  • Platform SDK Redistributable: CAPICOM

    • Then regsvr32 on capicom.dll… eg:


    cd "C:Program Files (x86)Microsoft CAPICOM 2.1.0.2 SDKlibX86"
    C:Program Files (x86)Microsoft CAPICOM 2.1.0.2 SDKLibX86>REGSVR32 capicom.dll
