Since yesterday I am trying Windows 7. Unfortunately Koff does not install and I figured out it has to do with the registration of winhttp.dll. Manually running the regsvr32 winhttp.dll command gives the following message:

The module "winhttp.dll" was loaded but the
entry-point DllRegisterServer was not found.

Make sure that "winhttp.dll" is a valid DLL or OCX file
and then try again.


Is there a way to circumvent this error so I can use Koff on my test pc? I realize I might be a bit too early with this question since Windows 7 is still in its beta state but there might simply be a quick fix of course. Smile

I'm also curious for a solution for this.

The current version doesn't install on Windows 7. Needs XP, Vista blah blah. I hate it (in general) when a setup is checking for specific OS's instead of version greater than... because this will cause trouble when upgrading to newer OS.

Installed it succesfully after making some changes with Orca (os check 1=1, deleted rows with winhttp). Even then it would roll back with no error display. However msiexec.exe /i "kerio-koff-6.6.2-7165-win32.msi" /qn /l .\k.log did the trick.

Edit: it seems that msiexec.exe /i "kerio-koff-6.6.2-7165-win32.msi" from (elevated, default at admin user) command line also works. Something to do with UAC...

^ Are you saying you succesfully installed koff? Because here those commands still produce the same error.

Btw, I also used orca to allow installation on Windows 7. Also tried deleting the winhttp line but that indeed only makes the installation to auto revert.

Even tried an older winhttp.dll version from Vista but the error stays. Guess there are some fundamental differences in the new Windows.

I'm happy to see your excitement about testing KOC with new systems. Support for Windows 7 will be announced once we will be able to test, verify and certify our product for this system.
Meanwhile, there will be still an issue known to every early-adopter - sometimes software has to be modified to support new system.

Do the Orca thing and search for the text winhttp. Drop all found rows. After that save the MSI and run it from an admin cmd. It works for me. The install log says "installed succesfully" and I have it running at this moment.

This method also works for the admin console.

When you install the admin console, before pressing OK at the 'wrong os' error, do a search in c:\users\you\ for 'kerio'

find the kerio-admin msi package and remove the entry in 'LaunchConditions' with orca.

Save the msi to your desktop and run it.

Et Voila, installs and works.

That's great news! Seems the solution really is quite simple. Smile Will try as soon as I'm back at the test pc.

Using Orca to remove the launch conditions and all winhttp rules from the installer and then installing the msi from a console with admin rights did the trick. Very Happy Thanks for all the tips!

Accidentally installed an older version of KOC but guess what: the auto upgrade went just fine. Wink

Could one of you guys post some step by step directions to get Koff running under Windows 7?

Some of us aren't as tech savvy. Smile

Thanks
