Download problems


Your browser may warn you that the type of file you are attempting to download may harm your computer. This is just a standard security notice that appears when downloading files of this type. Click OK to approve the download.

If your download doesn’t start correctly when you click on the download link, try the following:

  1. Move your mouse so that it points to the download link.
  2. Press the right-hand mouse button (right-click on the link).
  3. In the pop-up menu, select “Save Target As…”, “Save Link As…” or any similar menu choice.
  4. Select a suitable folder for the downloaded file. You may also change the name of the program file, but it’s probably simpler if you don’t.
  5. Click on the “Save” or “OK” button.
  6. The download should now start.


Some corporate networks have “firewalls” that prevent you from downloading software. This usually affects all downloads regardless of the source. We suggest you retry the download from your home computer.

Internet Security products

There are many “Internet Security” products for safe browsing, e.g

  • Symantec/Norton Internet Security
  • Kaspersky Internet Security
  • McAfee Internet Security
  • Trend Micro Internet Security

Some of these products may sometimes issue a warning that they cannot guarantee that SpreadsheetConverter is a safe download. There are no known security vulnerabilities in SpreadsheetConverter, so you can safely approve the download.

All our files and computers are scanned for malware at all stages of production using the latest versions of industry-standard Internet security software which is updated automatically. All files available from our Download page are free of known malware.

However, software detection is usually based on known “signatures” of malicious files and cannot detect new and unknown malware which may be working its way around the Internet. In order to provide additional protection, most Internet security software uses advanced techniques to warn their users of unusual behavior. Such “deep-scan” or “heuristic” features are typically much less exact than traditional signature matching and often result in false alarms which affect almost all legal, malware-free software. This is why you will often see strong recommendations to turn of Internet security programs during the installation of many software applications.

We sometimes get false positives for two programs, e2o2.exe and ViewManager.exe. When you use our Excel plugin we would prefer to run these programs close to Excel but unfortunately this may lead to memory leaks that are beyond our control. Therefore they are currently run as separate processes using the Windows Command Prompt. This is a short-term solution that solves a lot of problems but create a few others.

If your Internet Security software is flagging any other part of our software as malicious, we urge you to contact us immediately. But so far, all warnings that e2o2.exe or ViewManager.exe are behaving strangely or get a “suspected” status have been false alarms. We regret any inconvenience this may cause you and we are working on a long-term solution for this.

Macro security

If you have problems using SpreadsheetConverter after installation, you may be using high macro security with Excel. In this case, use Excel’s Tools menu to navigate to Tools> Macro> Security and set the macro security to Medium. You may also have to explicitly “trust” all Excel macros from Framtidsforum.
