Host wont run on Windows 8.1 64bit

lmclaren

I have tried to install and run 1.5.6 host on Windows 64bit 8.1. When I click the desktop shortcut to run, it goes busy for 5sec and then nothing.

I have tried running with administrator privileges, comparability settings, reinstalling, turning off one screen (I have 2) changing screen resolution, nothing helps.

I have tried launching directly from the executable, deleting the registry settings etc.

Are there any debug setting or suggestions?

many thanks.

I forgot to mention, I also tried to install the font.

Do you see anything? Any message? Messages in windows event log?

What graphic card and color resolution are you using?

Has anyone got any suggestions?

Are there any beta versions that I can test?

I have found the cause, it is to do with the FIPS encryption, needed for many vpn clients.

It would be nice if the Repetier could be fixed so I don't need to do this.

This key will turn it off so Repetier can run but stops the vpn client working,

This is to turn it off:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]

"Enabled"=dword:00000000

This turns it back on again.

<div>[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]

"Enabled"=dword:00000001

</div>

What a stupid thing. I googled after your comment and you are right. MD5 is not FIPS compliant so it simply stops working in that case crashing the app.

Modifying the registry is error prone so I do not like this approach. I think the better solution to have a own MD5 implementation that does not depend on anything. That way VPN will still continue to work. Will add this for next update.
