Hi,
 My OS is Windows 7, 64 bit edition, last night I installed an OS patch (some security update), today I when I tried to fire sonar as an administrator, I get a message saying 'Windows cannot find 'C:\Program Files\Cakewalk\SONAR X2 Producer\SONARPDR.EXE'.
Make sure you typed the name correctly, and then try again.' If I try to invoke it as a normal user I get the following error message
basically saying the file is not compatible with my current version of windows and to check if I need an x86(32-bit) or x64 (64-bit) version of the program.

 
What is the best course of action now, should I uninstall and re-install the program?

have you tried opening sonar with a 'icon' project?

Hi,
What do you mean by icon project? If you mean the projects that are listed by Sonar icon when I right click on the main sonar icon in the task bar, than I get the same compatibility issue message I mentioned earlier.

edit)i mean start sonar opening a CWP project..

Try the following:
 

1. Navigate to C:\Program Files\Cakewalk\SONAR X2 Producer\ within Windows Explorer
2. Right click on SONARPDR.EXE and select properties from the drop down menu
3. Click on the Compatibility tab
4. Enable the Checkbox under Compatibility mode "Run this program in compatibility mode for:"
5. Select Windows 7 from the dropdown list
6. Enable the "Run this program as an administrator" checkbox at the bottom (optional)
7. Click Apply, then OK.

 

Hi msmcleod,
 
I tried your suggestion. I am now getting a different error: "C:\Program Files\Cakewalk\SONAR X2 Producer\SONARPDR.exe is not a valid Win32 application."
 
One more thing, not sure if it's of any significance. After doing as per your suggestion I shut down the machine as I had to attend to some other matter. When I restarted the machine later, it went into the file system repair mode , even though I did not schedule for any repair work before shutting down. Upon restart and attempting to fire up Sonar, I got the error message I just mentioned above.

Try the following:
 

1. Navigate to C:\Program Files\Cakewalk\SONAR X2 Producer\ within Windows Explorer
2. Right click on SONARPDR.EXE and select properties from the drop down menu
3. Click on the Compatibility tab
4. Enable the Checkbox under Compatibility mode "Run this program in compatibility mode for:"
5. Select Windows 7 from the dropdown list
6. Enable the "Run this program as an administrator" checkbox at the bottom (optional)
7. Click Apply, then OK.

 

This sounds like SONARDPR.exe has been corrupted.
 
The question is how it got corrupted... First I'd do a disk scan, and after that run a virus check.
 
After that, re-install SONAR X2.

Try the following:
 

1. Navigate to C:\Program Files\Cakewalk\SONAR X2 Producer\ within Windows Explorer

 

I would do this, and then just try to run the .exe by double clicking on it.  At least that would rule out whether it is just the shortcut that got corrupted.  If it runs here, then you just need to create a new shortcut.

Hi,
 
I did that too, still getting:
"C:\Program Files\Cakewalk\SONAR X2 Producer\SONARPDR.exe is not a valid Win32 application."

Then have you followed the other suggestions to try compatibility modes and/or run as administrator?
