WinSteam 4.0, @Air 4.0, @Gas 4.0 and XLInterp 4.0 have been tested with Windows 8 and are fully compatible. The Excel add-ins for these products have been tested with Office 2013 and are fully compatible with both 32-bit and 64-bit versions of Excel. Previous versions of these products are not compatible with Office 2013.
We made a change to the installation programs for the 32-bit versions of all of our 4.0 products to make it easier for users to find the Excel add-ins. The previous versions of all of our 32-bit products placed the Excel add-ins in the Library folder of the current version of Excel installed on your computer. The new release of the 32-bit installation programs place the Excel add-in files in the corresponding TechwareEng product folder. This was done because the Office Library folder is difficult to find under Office 2013.
More specific details regarding the installation of the 32-bit versions of our 4.0 products are provided in the download and installation instructions for each product. No changes were made to any of the products' files.
The download file for the 32-bit version of @Air 4.0 has been replaced with a new release to fix a problem with the unit set extras. In the @Air add-in for Excel, the user can add extra characters to the unit set name in order to invoke specific changes to the functions such as changing from a dry basis to a wet basis for certain properties. In the previous release of the 32-bit version only, these unit set extra characters were ignored. The unit set extras were available when the user entered unit sets on a numerical basis instead of a character basis. This release fixes that problem. We suggest that all users of the 32-bit version of @Air 4.0 download the new version. You should un-install the previous version of @Air before installing this upgrade. You will have to re-enter the serial and authorization numbers.
The download file for WinSteam 4.0 has been replaced with a new release to fix a couple of minor problems. The first fixes the StmPHT function which was returning an error value in certain areas of the critical region. No other functions were changed nor was the StmPHT function code changed outside of the critical region.
A few customers were having problems getting the 64-bit version of Excel 2010 to recognize the WinSteam add-in. This new release also fixes that problem. The designation for the new release version is 4.0.1. You can verify the version number by clicking the About button on the DeskTop Steam Help menu. The StmVer function only returns the major and minor version number and so the release number is not visible from there.
All users of WinSteam 4.0 should download and install the new release. If you install it without uninstalling the previous release, you will not have to re-enter the serial and authorization numbers.

For all version 4.0 products, you will have to go to the TechwareEng group on the Start Menu to launch Help.
