Important information • Upgrade information • Before you install To avoid any problems, do not install this release in a directory where you have previously installed any older version of IAR Embedded Workbench.

It is recommended that you either uninstall an earlier product, or install this release in a separate directory. As before, however, it is possible to install different products, all using the same version of the main application, in the same root directory.

• License renewal The upgrade to this version might require a license renewal. This is performed by starting the IAR License Manager and selecting License>Check for License Renewal. Note, if you have a network license, this must be performed on the license server. • Microsoft Windows Windows Vista and newer operating systems have a security mechanism called UAC (User Access Control). Disabling UAC will automatically grant you permission when a task requires administrative rights but this is not recommended because it will reduce the security of the computer. It is not necessary to run the IAR Embedded Workbench IDE as an administrator. However, if you are not, modifications to the installed product tree in C: Program Files IAR Systems might not work as intended and could give unexpected results.

One example is opening and building projects directly from the installed product tree. The build will succeed, but the resulting files (object, list.) will not appear where expected. Instead all output files will be redirected by the OS to C: Users AppData Local VirtualStore Program Files IAR Systems. To avoid this, the preferred way is to copy the examples to a location outside Program Files, either manually or automatically by opening them via the IAR Information Center.
