At first, they just messed up and show a screen from a tetris program I installed. I deleted all the files that came with the tetris program and now pressing either button goes to a blank screen. I can enter values to be graphed, but the graph won't display anything except a cursor when I hold down an arrow key.
I enter an equation on the graph such as x^4-3x^3+6x-1=0 into Y1 and Y2 and I get an "ERR; INVALID DIM" but no graph.
Please help I have TI-84 Plus
even when i have all of the coordinates in, my graph doesn't work, it just says 'invalid dim"
Installation or uninstallation of an application or game fails and gives the following error code:
This issue is due to a previous installation not finishing properly
Solution 1. Rename the Installshield folder
Make sure you've enabled Show hidden files and folders.
Find and rename the Installshield folder:
Windows 32-bit: C:\Program Files\Common Files\Installshield
Windows 64-bit: C:\Program Files (x86)\Common Files\Installshield
If there is an Installshield file in the Common Files folder, rename that one also (e.g. to Installshield_OLD).
Solution 2. Remove all traces of previous uninstall
If renaming the Installshield folder had no effect, find and delete any traces of uninstalled applications.
Applications that can assist you are: Revo Uninstaller, Windows Installer Cleanup Utility , CCleaner.
Alternatively, do a manual clean-up:
Close all running programs. Then clear the Temp folder (found via input of %temp% in Start > Search or Start > Run).
Use the Windows registry editor to delete registry entries related to the program.
Restart the computer.
hope this helps
