You can try the start menu-> Run-> Regedit opens the registry-> Locate [HKEY _ Local _ Machine \ Software \ ESRI \ License], locate "License _ Server" and change its value to local host.
Solution 1:
Modify the service.txt under the bin (one of the files copied in when cracking) and modify the port number (originally 27000) (for example, 2700 1). Then "re-read the license" and you can run ArcMap. If not, I will uninstall licenseManager and reinstall it. After changing the local host of ArcGIS Administrator, I clicked the application. I don't know if it's ok. In addition, if you copy the ARCGIS.exe and service.txt in the decryption folder and replace the files in the bin under the LicenseManager's license 10.2, you may always be prompted to open the copied files in another folder. At this point, enter the LicenseManager to start/stop/reread the license, just click Stop, and the license can be reread after replacement. After all, sometimes you will follow the installation tutorial step by step at the beginning. When encountering problems, many details will be ignored if the installation is not uninstalled again. Even if you find a solution, you will encounter new problems, and then go online to check and solve them. There are really few unsolved problems on the Internet. As long as you keep looking and trying, you will always solve them.
Solution 2:
Is there "check the imgrd log file or try imre read" in the error log? If there is, there may be something wrong with img rd, so copy this from other children's shoes and replace your own.
There may not be many methods, but it really took two hours.
Arcgis engine must be successfully installed before 6: 30 tonight. Anyway, there are many problems now.
