Windows XP Compatibility of ACD/Labs software version 5.0

Note: All problems described below are for ACD/Labs software v. 5.0. Earlier versions are not supported at all. Version 6.0 and later is completely compatible with Windows XP.

The Windows XP represents the latest incarnation of Windows to be released by Microsoft. Current releases include:

Windows XP Professional
Windows XP Home Edition.

NO version of ACD/Labs software v.5.0 or earlier is GUARANTEED TO RUN under Windows XP. If you choose to install it on a Windows XP system, you do so at your own risk. Windows XP was not available at the time of development of release 5.0 (or earlier versions) and thus, the testing has not been extensive.

Known Installation Issues

These are provided for your information only, and should not be used as installation instructions.

1. All ACD/Labs software requires the ability to write to the Windows directory. This directory is protected under Windows XP unless you have Administrator privileges. These privileges are therefore required for installation and operation of the software.

   Configuration files for ACD/Labs software are written to the windows directory upon installation as well. The software will run with the default settings as installed; however any user preferences (such as default directories, new program locations, etc.) are written to these files. It is suggested that the Administrator grant Write and Modify privileges to users on the following files:
   acdbasic.ini, acdexe.ini, acdilab.ini, acdisis.ini, acdsoft32.ini.

2. For all of the components to install correctly, you must use Add/Remove Programs under the Control Panel. Exit the startup screen that loads when the CD is first placed in the drive. Start Add/Remove Programs from the control panel. The setup.exe program is found in the X:\install directory (where X represents the letter of your CD-ROM Drive).
    
3. ACD/Labs Chemist's Version software release 4.0 (and earlier) does not install at all under Windows XP. The Chemist's Version software includes:
   ACD/Lite Companion v.3.5
   CNMR Spectrum Generator v.4.5
   HNMR Spectrum Generator v.4.5
   IUPAC Name Generator v.4.5
   BP and VP Calculator v.4.5
   LogP Calculator v.4.5
   Solubility Calculator v.4.5
   pK_a Calculator v.4.5.
    
4. Aldrich NMR Library for ACD/Labs Standard and Pro, release 1.2 (and earlier) does not install under Windows XP.
    
5. Any ACD/Labs software that requires a HASP (dongle) to run WILL NOT run on Windows XP.

Dual Boot: ACD/Labs does not endorse such a configuration. If you absolutely need Windows XP, there are dual-boot options available that will allow you to have two Windows XP and Windows 9x or NT (Linux or Win3.x for that matter) on the same computer. Please refer to your Windows XP documentation for more detail. In this configuration, only one OS will be registered to run the ACD/Labs software package.
