Excel 97 Users Must Have SR-2 or Later
If you are still an Excel 97 user, after you have installed zCalc, you may experience error messages when you open the zCalc Tool Box or even when you open Excel (the most common of which is "Runtime Error 429: ActiveX component can't create object"). Do not despair. These errors are usually the result of old Excel system files that need updating.
To resolve these errors, make sure you have the Excel 97 Service Release 2 (SR-2) or later. It is required in order to run zCalc successfully. To see whether you have SR-2 and to obtain the latest service releases from Microsoft go to: Excel 97 Service Releases. NOTE: Make sure you reboot your machine and reinstall zCalc after installing SR-2.
