FAQ: Purchase Via SWReg

Be sure to specify an email address where the confirmation email message from SWReg will not be blocked a firewall or antivirus software.

FAQ: Download After Purchase

Within minutes after you finish purchasing at SWReg's web site, SWReg will send a confirmation message to the email address you specified when you purchased. In the lower third of that email message there will be a URL internet link where you can download the software.

The download link will expire after 7 days from the time of purchase, so be sure to download the software immediately.

In many email clients, e.g., Outlook Express and Eudora, you can click that link and the download will begin. Otherwise, you can copy the URL internet link from the email message and paste it into a web browser, e.g., Internet Explorer or Mozilla. If the link is so long that it wraps around onto another line in your email client, you may have to copy and paste the two segments.

The download file is a compressed ZIP file. To download the file, you may have to temporarily disable your firewall or antivirus software.

After you download the ZIP file, right-click or double-click it to extract the XLA, XLS, and PDF files.

On a Macintosh, double-click the ZIP file to extract the files.

FAQ: Install Add-In After Download

Launch Excel, and use Excel's File Open or Office Button | Open command to load the add-in XLA file or the example XLS file.

Do not double-click the add-in XLA file to load the file. Some of the add-in code may not be executed properly if you double-click the file. Instead, use Excel to load the XLA file.

Do not try to try to load the XIP file.

Refer to the How To Install Add-in PDF file for other ways to load or install the XLA add-in file.

FAQ: TreePlan Decision Tree Add-In

If you encounter error messages using TreePlan, please download a  Tryout version of TreePlan that is appropriate for some non-U.S. English versions of Excel. To do so, right-click tree164t.xla and save. The shortcut key for tree164t.xla is Ctrl + t (instead of Ctrl + Shift + t for tree173t.xla).

If you encounter error messages using TreePlan after you purchase TreePlan via SWReg, send e-mail to Mike Middleton, and I will send you TreePlan 1.64 that is appropriate for some non-U.S. English versions of Excel.

Current TreePlan versions use Control+Shift+T as the shortcut key. Previous versions of TreePlan used Control+t.

FAQ: SensIt Sensitivity Analysis Add-In

There are no known issues with SensIt 1.44. (SensIt 1.44 fixed a seldom-encountered bug when negative values are used as inputs for a spider chart. There were no changes to tornado charts from SensIt versions1.43 to 1.44.)

FAQ: RiskSim Monte Carlo Simulation Add-In

There are no known issues with RiskSim 2.41.

FAQ: Macintosh

After you purchase and download the ZIP file from SWReg, double-click it to extract the compressed files.

When you launch Excel and load one of our single-file add-ins, the add-in code detects whether it is running on a Windows or Macintosh, and the add-in then displays dialog boxes that are appropriately sized.
