Error or Warning Message

A message indicating that the software can't install or can't find the AccessDatabaseEnginex64 comes up during installation or at startup:

Information
Can't find AccessDatabaseEngine for x64.
You need install AccessDatabaseEngine before run AutoCAD version promis.e on 64-bits system.

Explanation

This error occurs when the 64-bit AutoCAD version of promis.e is installed on a system that already has an incompatible version of the Microsoft Office products installed.  Microsoft does not support and will not allow both the 32-bit and 64-bit versions of the Office suite of products to be installed on the same machine.  In order for the promis.e 64-bit version to truly operate as a 64-bit program, it requires the AccessDatabaseEngine_x64, as described in the Install Guide, and in the Compatibility Chart.

How to Avoid

• If you do not have the 64-bit version of AutoCAD and erroneously downloaded and installed the 64 bit version of promis.e, please uninstall it and install the correct 32-bit version. 
  Note: AutoCAD does not support running the 32-bit version of AutoCAD on a 64-bit OS, so if you have a 64-bit OS, and intend to run the AutoCAD version, it must be the 64-bit version.

• If using Microsoft Office 2010, install the 64-bit version of Microsoft Office 2010.

• If using Office 2007 which is 32-bit only, or Office 2016 64-bit, or Office 365 64-bit, or not using Microsoft Office, download and install AccessDatabaseEngine_x64.exe 2010.

• If you want to use the 64-bit version, but do not have a 64-bit version of Microsoft Office available, you could install promis.e on a machine with no Microsoft Office installed, and it would install the required Access Engine automatically.  Some users in the past have done this by setting up a Virtual Machine environment for promis.e so their main system could still have the 32-bit Office version.

• You could switch to the Standalone version of Promis.e which does not use an AutoCAD based engine, and does not have this limitation on 64-bit Operating Systems.  It will run on either a 32 or 64-bit OS, with no restriction to the Office version.  

• If the error message still appears after AccessDatabaseEnginex_64.exe has been installed or otherwise appears in the program list in Control Panel, uninstall it using Control Panel > Programs and Features and reinstall it.
