In Windows 8, when ADS1.2 is installed, the system prompts "error starting external process: process error code (0x87)". 1. Find the ADS1.2 installation package, right-click SETUP in it. EXE, select properties, and select -- "run this program in compatible mode" and "run this program as administrator", OK; 2. run SETUP. EXE to install the software. 3. After installation, go to the installed directory C: \ Program Files \ ARM \ ADSv1_2 \ bin, and modify the attributes of ied.exeand axd.exe in the same way, select -- "run this program in compatible mode" and "run this program as administrator", and then click OK. After this operation, you can test the program by yourself. Note: The best installation directory is "C: \ Program Files" to avoid installation in the "X: \ Program Files (x86)" directory )". In special circumstances, you can refer to the suggestions of netizens: 1. Run as administrator: "All Programs-Attachments", right-click "command prompt" and select "Run as administrator ", enter the command "net user administrator/active: yes" and then log out or restart the system to use the super administrator account. (Note the space !) Open the control panel and click "user management" to view the Administrator account. Select this account and set a new password. Do not use the default password-free status! After the installation is complete, change "yes" of the input command to "no" to resume normal user login. 2. If the preceding step 3 does not work after modification, select computer> Management> services and applications> services> Desktop Window Manager Session Manager> right-click Properties> Startup type> disable, the preceding operations must have administrator privileges. Note: I have not met the above two steps. If this operation is successful, please leave a message and give me more advice.
