How to resolve: Error Code: 711

Many of our TDS clients face this issue while opening the AP Invoice/Payments Screen, below is the message popped up.

 “Error code: 711 Invalid class string. Looking for object with ProgID ” (refer below screen shot for error).

We have arrived at some conclusions regarding this cause of the issue as listed below:

• The respective file is not registered in the registry OR
• User may do not have the sufficient rights to use the AP module

To solve this error you need to do the following steps:

1. Close the Accpac, if it is in running mode.
2. Examine the user right for Sage Accpac folder, if not defined then please give the rights to the user.
3. If the operating system is window 7/window vista then make user as a power user. 
4. Execute the RegAcc.exe as administrator [you will find this in sage Accpac installable folder i.e. C:\Program Files\Sage Software\Sage Accpac\Runtime]

 Hope this helps!
