Crystal Reports Error: Attempted to read or write protected memory.

Question

Sage 300 Advanced ERP 2012 PU1 
 Windows 7 Professional - All latest updates installed. 
 Microsoft Outlook 2010 
 On one workstation only, when printing invoices to e-mail from the A/R module the first invoice processes as normal. The second and all subsequent invoices give the following error. 
 "Description: Crystal Reports Error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt." 
 
 If I exit Sage 300 ERP and login again I can send one more invoice then the problem returns for all subsequent invoices. 
 Any assistance would be greatly appreciated.

At the end of the day this seems to be a Windows 7 (64-Bit) compatibility issue. It was resolved by inserting the following registry entries on each workstation (forcing Accpac to run in Windows XP compatibility mode): 
 [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers] 
 "\\...Insert your program directory path...\Runtime\accpac.exe"="WINXPSP3 RUNASADMIN" 
 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers] 
 "\\...Insert your program directory path...\Runtime\accpac.exe"="WINXPSP3 RUNASADMIN" 
 There is of course other means to accomplish the same end result as the registry entries identified above. 
 As the error message itself is not indicative of a compatibility issue it may be so generic that could represent a wide variety of error conditions. (i.e. This solution may or may not work for you.)
