[Mod-security-developers] IIS install issues

[Corbin G. <co...@gm...>]

I'm doing a first time modSecurity install on a Windows 2008 R2 SP1
server.  When I run the 64 bit installer, the installation fails.   Looking
in the event log, it gives

Product: ModSecurity IIS -- Error 1722. There is a problem with this
Windows Installer package. A program run as part of the setup did not
finish as expected. Contact your support personnel or package vendor.
Action InstallModule, location: C:\Program Files (x86)\ModSecurity IIS\,
command: "C:\Windows\SysWOW64\inetsrv\appcmd.exe" install module
/name:"ModSecurity IIS"
/image:"C:\Windows\SysWOW64\inetsrv\ModSecurityIIS.dll"

Ending a Windows Installer transaction:
C:\Users\Administrator\Downloads\ModSecurityIIS_2.7.7-64b.msi. Client
Process Id: 3308.


I downloaded and installed the 2013 vcredist prior to beginning the
install.  I have tried re-running the msi installer, rebooting, etc. but
each time the install fails with the error above.

Any ideas of what's happening?
