Recent Windows 7 updates crashed Paradox 11?

I dual boot WinXP Pro X32 and Windows 7 X64 Pro on separate drives and run Paradox 11 from WP Office X3 on both.  I mostly use XP and  there are no problems with Pdox after those updates but when I went to use it under Windows 7 today the Project Viewer showed no files in the working directory. Until now there was no problem with the Windows 7 installation.  I uninstalled and reinstalled Pdox and then tried to set Project Viewer to the proper working directory and it crashes.  I've tried this several times.  If I open a table with Explorer Pdox will start and open it but if I try Project Viewer it crashes.  I went to check the BDE settings but I can't seem to find BDE in the control panel or anywhere else in Windows 7.

On the files issue, I wonder if you're running into Windows 7 application virtualization. I installed a Windows 7 manifest to work around that. Have you tried that?

Also, take a look at my running Paradox 10/11 on Vista post for some tips:

As for the crashing problem, if that was happening to me, I would reinstall over Paradox. If that didn't fix it, I would do a clean install.

Thank you for the fast response.  Paradox 11 work fine under Windows 7 when I first installed it.  As to "Windows 7 application virtualization" if you mean am I working in Windows XP mode, no, I am not.  I also don't know what a Windows 7 manifest is.  When I tried reinstalling Paradox, I first tried installing over it as a repair and then when that failed tried a clean install at least twice.  As I mentioned before, I haven't been using 7 that often lately but I only noticed this problem after the last batch of Windows updates.

>>..."Windows 7 application virtualization" if you mean am I working in Windows XP mode, no, I am not.

Not XP mode. Windows Vista and 7 introduced some new concepts we all need to be aware of, application virtualization is one of them. The following is from my Install Paradox 9 on Vista article:

Application virtualization was introduced with Vista and creates application-specific copies of all shared resources. It separates the application configuration layer from the OS making deployment easier in some cases.

Application Virtualization Symptoms:

• Change your working directory to the default samples folder. (If you're in WPO 2000's Paradox 9, that directory is located at C:\Program Files\Corel\Shared\samples.) Create a form in Paradox and save it to that folder. Now go out to Windows Explorer and try to find the file, you can't because it's been virtualized for the specific instance of Paradox running and exists only for that application.
• One more example, create a form that exports a spreadsheet. In the Project Viewer, switch to the Custom View. You should see your spreadsheet in the Project View. Try to open the spreadsheet, you can't. Even though you can see it in the Project Viewer, application virtualization has made a copy of it specifically for Paradox. When the file is passed to Excel, Excel can't find it.

Solutions to defeat application virtualizaion:
If you want to make your application data available to multiple users of a single computer running Windows Vista, you can...

1. Place the data in a sub-folder of the Public folder.  Vista does not virtualize this folder and it is available to all users on a PC. 
2. You can also set the permissions on the files or folders you want to share to allow all users full permissions.
3. Run Paradox as an Administrator (perhaps even deploy a manifest file).

By default, Paradox puts certain folders like the samples folder mixed in with the program files. You need to move those folders to a folder that is NOT virtualized such as your Public folder. If you don't, then you should at least be aware of what it does. Or, grant those folders full rights.

>>...I also don't know what a Windows 7 manifest is. 

Windows Vista and 7 run programs with limited permissions. Sometimes applications require or benefit from a higher security permission level. Try right clicking on the Paradox icon and select Run As Administrator and see if the symptom still persists.

If running as administrator fixes the problem, you can distribute a Windows Manifest file in your environment to permanetly fix the problem.

Here is a copy of the pdxwin32.exe.manifest file I have on my personal Vista notebook (in my C:\Program Files\Corel\WordPerfect Office 2000\programs folder).

I don't think application virtualization is the problem. I changed compatibility settings as well as run as administrator but it always comes down to the project viewer.  Every time I try to change the working directory from the installation default to the folder I want, I get an "unspecified error" window for pdxwin32.exe followed by numerous "access violation" errors for pdxvwr32.dll.  The first time I installed Paradox 11 it worked fine.  At that time I was also able to remove pdxregcl from the registry and my settings were saved. Now, that doesn't work either.  I finally found BDE but changing those settings didn't  help either..

As I said before, if I don't use Project Viewer Paradox works fine but I don't understand why I have to do that.

I'm back to square one after uninstalling /reinstalling Paradox at least 10 times.  I finally was able to get rid of pdxregcl and by avoiding Project Viewer was able to set my working directory to my proper folder.  Still, Project Viewer is still empty even though the working directory is correct.

In going back over postings related to Project Viewer, I tried moving about half of the over 800 files in my working directory to a temp folder.  Sure enough, I could then see the remaining files in Project Viewer.  When I moved the other files back Project Viewer is empty again!  I reference the same working directory folder in my Win XP Pdox 11 installation and Project Viewer sees it.  What gives with Windows 7?  Can there somehow be a limit to file number or directory size in the Project Viewer under 7 that doesn't affect XP?

Hi Con,

What is the current path to your working folder?

Also, do me a favor, create a new folder in your Windows 7 public folder, perhaps called PdoxWork. Then, copy all 800+ files to that new folder. Finally, change working directory to that public folder (probably C:\Public\PdoxWork\). Can you see the files in your Project Viewer now?

I just tried system restore using a point before the recent updates but still no luck.

I was having the issue on Win7 32bit that pdx exited with this error and I did the steps to move my working directory to the public folder and NO MORE ERROR!

Wow great job man keep up the good work!
