Preparing a Windows environment

This topic provides information about preparing a Microsoft Windows environment before installing.

Permissions required to run the installer

To run the installer on Windows, you must have administrator access.

To run in non-admin mode, you must have write access the %windir% directory and the install location.

Temporary disk space

You should have 1.5 GB of free temporary disk space. If the temporary space on Windows is less than 1.5 GB, you can optionally set the IATEMPDIR or the TMPDIR environment variable to point to a directory that has sufficient disk space. The installer uses the IATEMPDIR variable to assign the location of a temporary directory to use during installation. If your Temp directory does not have enough free space to run the installation, it will fail.

If you have access to another drive or partition with more free space, set a new temp directory by using one of the following commands:

```
export IATEMPDIR= <pathName>
```
```
setenv IATEMPDIR= <pathName>
```

In these commands, <pathName> is a writable directory with more free space available than the default directories.

Note

The installer gives the first preference to the IATEMPDIR environment variable. If it is not available, it uses the TMPDIR environment variable.

Terminal Services Configuration options

If you are using Terminal Services, update the Terminal Services configuration options as needed before running the suite installer; otherwise, the installer will not run. Use the Group Policy Editor option to configure Terminal Services.

If you are using the data execution prevention (DEP) feature in Windows Server, you must configure DEP for the BMC Remedy AR System installation executable.

The following topics are provided:
