GeoTools V10 runs under both 32-bit as well as 64-bit versions of Windows Vista or XP.
The installation procedure and the interface is identical in 32 and 64 bit operating systems. The installer takes care of all the OS issues. However, in some 64-bit Windows, at the end of the standard install procedure, you might see a message 'No valid AutoCAD installations were found' even when one or more valid AutoCAD's are successfully running. This is a bug in the AcadInstall program or in Windows setup itself that displays this misleading message. It does not happen on ALL 64-bit OS and is random.
The solution to get around this problem is simple. Just do a manual configuration of GeoTools in AutoCAD as explained in the 'GeoToolsReadme.Txt' file to get GeoTools up and running on AutoCAD again.
I have reproduced the relevant section from the 'GeoToolsReadme.TXT' file so that you know exactly what to do if you run into problems:
----- GeoTools INSTALLATION for AutoCAD -----
1. Starting GeoTools: During installation, if you have chosen the AutoCAD profile to use with GeoTools, there is nothing else that you need to do in order to start using GeoTools. Simply start AutoCAD with the chosen user profile and you should be able to start using GeoTools.
2. If you did not do the GeoTools startup configuration during Setup, you will still be able to configure AutoCAD for GeoTools manually. To do this, start the "OPTIONS" command (Tools->Options...) menu and go to the "Files" tab and open the "Support files search path". Click on "Add" and then "Browse", then point to the location where GeoTools has been installed. By default, the installation program would have installed this under the "C:\Program Files\Four Dimensions\GeoTools" folder.
3. If you have other third-party applications, there are various ways in which you can manually tailor your GeoTools startup.
a) If you do not already have an existing ACAD.LSP, you can use the ACAD.LSP supplied with GeoTools. This would automatically load GeoTools program and menu as soon as you start AutoCAD. If you wish to be prompted whether to have GeoTools loaded or not, please comment the appropriate commands in the ACAD.LSP file as explained in the 'commented notes' within ACAD.LSP. Once loaded, GeoTools can either be loaded or unloaded using the GT_LOAD and GT_UNLOAD commands respectively.
b) If you already have an existing ACAD.LSP, you can either copy the contents of the GeoTools provided ACAD.LSP to merge with your pre-existing ACAD.LSP or you can load GeoTools separately by first loading the loader program GT_LOAD.LSP and then using either the GT_LOAD or GT_UNLOAD commands to either load or unload GeoTools.
4. Troubleshooting tips:
a. Ensure that the GeoTools folder is ahead of other support folders. When AutoCAD starts acad.lsp from the GeoTools folder should get executed. If there is an acad.lsp in another folder ahead of GeoTools, that would get executed and could possibly be a reason why GeoTools is not intitialized.
b. Ensure that the ACADLSPASDOC system variable is set to 1. If this is set to 0 in your AutoCAD, GeoTools may not initialize automatically in subsequent drawings opened if you have multiple documents interface turned on and you will need to manually load it in each drawing. The setting of ACADLSPASDOC to 1 ensures that it is loaded in all documents automatically.
GeoTools makes extensive use of dialog boxes, some of which are wide in size. It is therefore recommended that you use a Windows display screen resolution of 1024x768 or more. If you encounter "Dialog too big to fit the display" error, either increase the resolution or use "Small Fonts" in your display settings.
