Operating systems

CostAdviser Professional requires Microsoft's Windows 10. It will not run correctly on older version of Windows.

If you do not have it installed you can download and install the latest version manually from the Microsoft Net Framework website.

Windows security warnings

When you try and install CostAdviser Professional, you may get a message from Windows warning against installation. This message is generated by Microsoft by default simply because our app is not well known to them - it is a small-scale, highly-specialised app and not widely distributed. We can assure you that our app is legitimate and safe and has an authorised Digital Signature Certificate to prove its authenticity, which you can view by following the instructions stated further down this page.

To assist in the installation you can do the following:

• Locate the downloaded CostAdviserSetup.exe program on your computer
• Right-click it and click 'Properties'
• Under the 'General' tab tick the 'Unblock' check box and then click the 'OK' button.

Windows SmartScreen

If you receive a Windows SmartScreen warning for the reasons described above, you can use the following steps to bypass SmartScreen and install the program:

• When prompted by the 'Windows protected your PC window', click 'More Info'
• Click Run anyway
• If prompted, click OK to proceed with installation.

Norton Antivirus/Security

We are aware that Norton Security's Data Locker will sometimes interfere with the clean up operation when CostAdviser has been installed. The clean up procedure is part of the CostAdviserSetUp procedure and attempts to delete the temporary installation files used as part of the installation process. This is normal activity and a way of cleaning your computer of an unnecessary file. The file is in your Windows App Data temporary folder and is called CostAdviserSetUp.tmp

The blocking of the removal of this temporary file does not effect the installation of CostAdviser - that has all gone fine. It is purely the attempt the clean up afterwards that is affected and is not a crucial part of the installation procedure. If you run a program that cleans up your temporary files, that program will probably clean up this file anyway.
