1. Before installation, you may need to temporarily disable virus protection software such as Windows Defender.
The " Microsoft Access Database Engine 2010" is required, and
the framework uses　.NET Framework 4.81 . These can be obtained from the Microsoft website.

2. Installation is automatic when you run " setup.exe " in the distribution folder "Tera Calculation Inst." The installation location is C:\Users\ User Name \AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Microsoft . After installation is complete, { Tera Calculation Menu Screen} will appear in the "Recommended" section of the Windows menu . Click { Tera Calculation Menu Screen} to start Tera Calculation. 

3. Before launching the software, copy the attached " Tera Calculation Data " to any of the following locations : D :\, E:\ , or F: \ . Copying it to multiple drives on the same PC will result in an error when the software starts. You can copy it by changing the directory name, such as " D:\Tera Calculation Data Copy . " The software will automatically recognize " Tera Calculation Data ." 

4. Please resolve any installation issues yourself.　We recommend backing up your C: drive ( OS drive) before installation . Tera Calculation can be used without the Office Access software , but without the Access software, you will not be able to view tables or perform other Access -dependent operations.
