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.

• After installation
  If you are using the parallel port version of the FET tool (e.g. TI's MSP-FET430PIF), a restart of your PC is required to start proper operation of the DriverX parallel port driver.
• Migration
  

  Project files generated by version 3.x or newer of IAR Embedded Workbench for MSP430 can be opened by the project manager in this version of the product. Project files generated by version 1.x and 2.x can also be opened but the debugger settings will however be lost and must be set again.

  If you are migrating from version 2.x or later to this version we recommend that you take a look at the IAR Embedded Workbench for MSP430 Migration Guide for detailed information.

  If you are migrating from version 1.x to this version, you can use the Step by step migration for descriptions on how to convert your old projects.

• Upgrade from Kickstart to the full version
  It will be possible to use a Kickstart project without modifications in the full or Baseline version of IAR Embedded Workbench for MSP430.

• The IAR XLINK Linker, IAR XLIB Librarian and IAR XAR Library Builder have been moved from the common\bin directory to the 430\bin directory. Related documentation files and code examples have been moved to 430\doc and 430\src\xlink respectively.
• Windows Vista and Windows 7
  

  Windows Vista and Windows 7 have a new security mechanism called UAC (User Access Control). Disabling UAC will make Vista/7 work more like XP, 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 Vista/7 to C:\Users\<user name>\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.
