DV1147 - Not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

The information in this article applies to:

• DOVICO Timesheet
• Windows Vista 64-bit
• Windows Server 2003 64-bit
• Windows Server 2008 64-bit

Symptoms:

Unable to run reports on a Windows 64-bit OS server and the user receives this error below:

not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

Cause:

Crystal Reports cannot read the 64-bit .dll of the operating system since it is a 32-bit application.

For Windows Server 2003 64-bit

Resolution:

        Enable IIS 6 to run 32-bit applications

1. Ensure ASP.NET is allowed in Web Extensions
2. Go To Start/Run and type cmd then hit enter.
3. Enter the following command:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs set w3svc/AppPools/Enable32bitAppOnWin64 1

4. Register the 32-bit ASP.NET 2.0 to IIS (look in C:\WINDOWS\Microsoft.NET\Framework\v2.0.xxxx) by entering the following command:
   aspnet_regiis.exe -i -enable
5. Restart the World Wide Web Publishing service.
6. Go to your IIS administration console to the Web Service Extensions folder and ensure that asp.net v2.0* (32-bit) is allowed.
7. Login to DOVICO Timesheet and you should now be able to print reports.

Warning:  Due to limitations in IIS 6 which do not allow 32-bit and 64-bit applications to run simultaneously on the same server the steps above may cause other ASP.NET applications on your machine to stop functioning properly (64-bit only ASP.NET apps may no longer work). Revert IIS 6 back to 64-bit mode if that is the case, see instructions below.

Revert IIS back to 64-bit mode using the command below if necessary:

             cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

For Windows Server 2008 64-bit & Windows Vista 64-bit 

Enable IIS 7 to run 32-bit applications

1. Go to Administrative Tools, Internet Information Services (IIS) Manager
2. Right-click on the DOVICOTimesheet application pool
3. Select Advanced Settings
4. Set 'Enable 32-bit applications' to True
5. Click OK
6. Restart the DOVICOTimesheet application pool
