GraphPad Prism 7 Keygen Archives

This FAQ provides instructions to delete the serial number file in Windows.  The instructions to delete the serial number file on a Mac is presented here. The serial number file is also the license file. They are one and the same.

The Prism 7 and 8 serial number file is named:  prism-license.qxt

The Prism 5 serial number file is named:  ssprism5.qxt

Removing the Prism License File

As part of the activation process, you will need to reenter your serial number.  To delete this file, you will need to be logged in with admin rights. In Windows Vista and Windows 7, the file is hidden, so you need to change your file preferences to show hidden files.

Problem. In rare cases, the file prism.exe "disappears" after installation or update

A few Prism users have told us that prism.exe file disappeared after updating to Prism 7.05 version and restarting a computer.

This is not a Prism problem but a Windows problem. There are several postings on the  Microsoft forum, where users complain about this issue when Windows deletes other programs without notifying.

The most probable reason is that Windows Defender falsely detects Prism.exe as malware (false-positive) and so removes the program file (without giving any message or warning). 

How to fix

Step 1: Add Prism folder as an exception to Windows Defender or any other antivirus program

You can feel safe about using Prism. We checked Prism with many antivirus tools and none of them reported any malware alerts. We are quite sure that this reaction of Windows defender is a false positive (incorrect). We are posting this FAQ in early October 2018 and we expect that the problem will soon be solved by Microsoft. 

If you use Windows Defender, here are the steps to white-list Prism (so it won't get flagged as malware);

1. Go to Start > Settings > Updates & Security > Windows Security > Virus & threat protection > Virus & threat protection settings > Add or remove exclusions.

2. Under Add an exclusion, locate the GraphPad folder and click Select folder. The exclusion will apply to subfolders within a folder as well.

If you use other antivirus programs, of course, the details won't be the same. 

Step 2: Reinstall Prism

It is safe to uninstall Prism. You will not need to reactivate the license. Here is how to do it:

- To uninstall Prism click Start, Settings, Control panel, Uninstall a program (If sorted by categories). If the list is sorted by icons, select Programs and Features. Then select GraphPad Prism and uninstall it.

- To install Prism again you may find the installation file in My Account if you are a subscriber. Or find the email you received when purchasing Prism ("Thank you for ordering from GraphPad Software") and click the "Download Now", if you have a perpetual license. 

- You can also try installing Prism to a location other than "Program Files". If you have more than one disk in your PC - try installing Prism to a non-system drive.

Other things to try

Restore Windows

Restore Windows to an earlier date from the point you might have previously created.

System Restore is a Windows feature that can help fix certain types of crashes and other computer problems just by restoring Windows to the last working point. 

Here is how to restore Windows:

- To use the Restore Point click Start > All Programs > Accessories > System Tools. 

- Select "System Restore" from the menu

- Use "Restore my computer to an earlier time", and then click Next at the bottom of the screen.

Clean boot

Start Windows by using a minimal set of drivers and startup programs after you reinstalled Prism to see, if it was not deleted again.  

It helps to troubleshoot error messages and other issues and eliminate software conflicts. This kind of startup is known as a "clean boot." 

Here is the link with the detailed explanation on how to perform clean boot and it also contains the steps for determining what exactly causes the problem:
