SYMPTOMS
After you install the free version of Pretty Good Privacy version 7.03, you may be unable to browse the Internet or connect to an IP-based network. When you try to establish a Dial-Up Networking or RAS connection, you may receive the following error message:

Unable to Negotiate Connection

--

PGP Error

Cannot establish connection with the PGP SDK service.

[OK]

When you try to start PGPTray and PGPKey, you may receive the following error message:

Launching PGPDisk:

--

PGPDisk

The PGPDisk application could not start because: &quot;PFLError #-11939.&quot;

[OK]



CAUSE
This issue can occur because Pretty Good Privacy 7.03 is not compatible with Microsoft Windows XP.



RESOLUTION
To resolve this issue, reset TCP/IP in Windows XP. For more information about how to reset TCP/IP in Windows XP, click the following article number to view the article in the Microsoft Knowledge Base:

299357 How to reset Internet Protocol (TCP/IP) in Windows XP

If resetting TCP/IP does not resolve this problem, run System Restore. To run System Restore, follow these steps:
 * 1) Click Start, point to All Programs, point to Accessories, point to System Tools, and then click System Restore
 * 2) Click Restore my computer to an earlier time, and then click Next.
 * 3) Choose a time and date that is earlier than the date when you installed Pretty Good Privacy 7.03, and then click Next.



STATUS
This behavior is by design.



MORE INFORMATION
Note that if you uninstall Pretty Good Privacy 7.03, the issue is not resolved because the program uninstalls the TCP/IP stack, and the TCP/IP stack does not support manual reinstallation.
