Encryption Error Message “Level Symmetric”

Asked By 200 points N/A Posted on -

Hello! All of you here,

I have a problem appearing when I launch a remote connection item that uses a symmetric encryption.

An error message box appears as the following:

Cannot launch because encryption level Symmetric
cannot be initialized
CryptoAPI is not available.
Object already exists.

I want to delete this message or stop it from appearing. I think that this problem appears because of PC Everywhere cannot run in symmetric mode and the CryptoAPI may be broken.

I think that it is a general problem now on several Win2K Server systems. When trying to start PC Everywhere in host mode this can be caused by corrupted files in one of two locations.
Can you help me?

Thanks in advance.
