Requirement: - HMIWorks Standard version 2.05 or above (setup.exe) - The update.exe requires users to PRE-INSTALL setup.exe. Definitions of setup.exe and update.exe: - setup.exe refers to HMIWorks_STD_v2.05.08_setup.exe or the same like. The installation file that has "setup" in its name contains the whole data of HMIWorks. - update.exe refers to HMIWorks_STD_v2.05_Update_10.exe or the same like. The installation file that has "update" in its name ONLY contains certain files that need to change the original HMIWorks setup install. It is patch file to update the setup install. For example: The HMIWorks_STD_v2.05_Update_3.exe (Update #3) is used to update the previous versions of HMIWorks setup install, e.g. versions: v2.05, v2.05.01, v2.05.02. After installing the update #3 to the same folder of the above versions of HMIWorks, then the above HMIWorks becomes v2.05.03. FAQ: Q: Should I install update #1 and #2 before installing the update #3? A: No. The update #3 includes all updates in update #1 and #2. Q: Can I install v2.05 update #n with versions that is not v2.05.xx? A: No. The v2.05 update #n supports v2.05 series only. So does 2.06, etc.
