I was running Windows XP when I bought DVD MovieFactory 7 Pro.
Since I don't have any Windows XP machines running now, I had to reinstall in Windows 7 Professional.
The install into Windows 7 had roadblock after roadblock!
After a few hours of fighting the error messages I got MovieFactory 7 Pro going in Windows 7.
Here were the steps I had to take:
1. run the DVD MovieFactory 7 Pro installer
2. enter my purchase key
3. go download the MovieFactory 7 patches at https://www.videostudiopro.com/en/support/updates/
4. run patch 1, the 3-in-one patch
5. run patch 2, for Windows 7 compatibility
Then, I found that MovieFactory crashed with a DLL error message when I tried to open a video file.

This occurs when there are multiple versions of Intel openMP library DLLs on your computer.
Intel's steps of how-to fix the problem are clearly detailed on this Cyberlink webpage.

6. follow the steps for Windows 7:
After the Intel DLL problem was fixed, another DLL problem was unveiled:1. Click Start > Control Panel.
2. Click System and Security > System > Advanced Settings in the left pane.
3. Click Environmental Variables at the bottom of the dialog box.
4. In the User Variables section, click New.
5. Enter the variable name KMP_DUPLICATE_LIB_OK (name must contain capital letters and underscores).
6. Enter the variable value TRUE and click OK.
7. In the System Variables section, click New.
8. Enter the variable name KMP_DUPLICATE_LIB_OK.
9. Enter the variable value TRUE and click OK.
"Error: 'No DLLS were Found in the Waterfall Procedure'"
I did some searching and found this was related to having GoPro Studio loaded on the PC.

7. I moved these files to a folder I named "quarantine" and rebooted.In some cases after installing GoPro Studio, other applications may report an error that states: "Error at loading if ippSP library - No DLLS were Found in the Waterfall procedure".
If this occurs the solution is to browse to: C:\Windows\SysWOW64 and then remove these files:
ippcore-6.1
ippj-6.1
ippjw7-6 .. 1
IPPS-6.1
ippvc-6.1
After performing all these steps, DVD MovieFactory 7 Pro finally worked on my Windows 7 PC.
Best wishes!
