Why do the buttons not work, or why do I get the run-time error "Object doesn't support this property or method" when using the Arria 10, MAX 10 or Cyclone 10 PowerPlay Early Power Estimator (EPE) tool?

Due to a Microsoft security update, users may experience one of the following symptoms when using the Arria® 10, MAX® 10 or Cyclone® 10  PowerPlay Early Power Estimator (EPE) tool:

1. Buttons do not work
2. A run-time error "Object doesn't support this property or method"appears after opening the EPE

To work around this do the following:

1. Close all Microsoft Office applications including Excel and Word.
2. Open a Windows Explorer, and enter "%temp%" (without quotes) into the address bar.
3. Press "Ctrl" "F" and enter ".exd" (without quotes) into the search box.
4. If any files with extension ".exd" are found, select and delete ALL found files.
5. Next, enter "%appdata%" (without quotes) into the address bar. Again, press "Ctrl" "F" and search for ".exd", and delete ALL found files.
6. Reopen the EPE.

If the issues remain, please follow these steps:

1. Open the EPE, go to "File" -> "Info" -> "Compatibility Mode" and click the "Convert" button
2. If a pop-up appears, click "OK" to proceed with conversion, and then click "Yes" to reopen the workbook

The previous steps convert the original ".xls" EPE file into a ".xlsm" file. The newly created file should not exhibit the original issue.
