Getting the Problems off the Table

How many times has this happened? You receive a very important document from a lawyer that has updates that need to be compared to an older version. You set out to compare the two documents, and half way into your comparison the process abruptly stops and an error appears:

“The Comparison process was unable to complete. The process may have been interrupted or an error may have occurred.”

Tables can cause comparison issues and this is the reason why these documents won’t compare. It is because there are tables in these documents that are long and can cause complications with Word’s compare. Microsoft has noted this issue within MS Word 2007 and MS Word 2010.

How long is “long”?

Microsoft has noted that when you compare two Word documents and both have a table that contains more than 128 rows, the compare operation can be expected to take a long time, and you can even expect to receive the following error message: 


But how am I supposed to reduce the table length?!

Not to worry, you certainly do not have to start butchering your document to reduce the size of your tables. This is a problem that Microsoft has graciously provided step-by-step changes to your registry to allow your documents to compare without making any changes to them.

Here are the steps directly from the Microsoft Knowledge Base Article:

After you install the hotfix package, follow these steps to enable the hotfix:

  1. Click Start, click Run, type regedit in the Openbox, and then click OK.
  2. Locate and then click the following registry subkey:


  1. On the Editmenu, point to New, and then click DWORD (32-bit) value.
  2. Type DocCompareLargeTables, and then press ENTER.
  3. In the Detailspane, right-click DocCompareLargeTables, and then click Modify.
  4. In the Value databox, type 1, and then click OK.
  5. Exit Registry Editor. 

Compare Quickly and Easily

With these changes, you can tackle documents with large tables!

If the registry is scary and unfamiliar territory, you can always contact Microsystems and the Solutions Center to work with you to make these changes.
