- Note for users of Macs with the M1 architecture: There are some known issues with running late models of Excel on Macs with the M1 architecture and these result in run-time errors when trying to run PRC. The bottom line is that you must run Excel with Rosetta to avoid this problem. You do this via Finder > Applications > Excel > Get Info > click “Run with Rosetta”. The following link provides information regarding the workaround from Microsoft: https://pralanaretirementcalculator.com/community/issues-and-potential-errors-in-the-tool/run-time-errors-on-mac-m1-configuration/#post-687.
- Note for Excel 2010 Users: Your Excel configuration needs to include Microsoft Service Pack 2 (SP2). Without this, Excel may tell you that the PRC file is corrupted.
- Note 1 for Excel 2007 Users: Your Excel configuration needs to include Microsoft Service Pack 3 (SP3). Without this, Excel may tell you that the PRC file is corrupted.
- Note 2 for Excel 2007 Users: The digital signature is not recognized by Excel 2007 and will be reported as an invalid signature. This is due to the fact that Excel 2007 has not been maintained by Microsoft since 2012 and is no longer compatible with the newer security software technology used to produce the Pralana Consulting LLC digital signature. The workaround is to create a new folder on your Windows system into which you place the PRC file. Then, via Excel’s Trust Center, you specify this folder as a Trusted Location.
- Note for Internet Explorer 11 users on Windows 10 machines: PRC downloads may fail to work with this configuration. The workaround is as follows: On the IE11 page, go to Tools (the cog in the upper right corner), then Safety, then “Turn Off Windows Defender SmartScreen”. You can then turn this back to the “On” state when the download is completed.
- Note for Firefox users: Some versions of Firefox append a .xlsx extension to Pralana’s .xlsm files which Excel will reject. If you see this occurring following a download, you will need to manually delete the .xlsx extension from the filename prior to opening.
