While Installing MS CRM 2016 Online SSRS reporting extension. I got the following error. First I did the obvious, I restarted the system however that did not help. Soon I realized that the issue was not related to reboot rather it was an issue with the installer. I opened the file as instructed in the error below 

 
The error files contained the following log
22:35:38|   Info| === Setup bootstrap logging ended 6/22/2016 10:35:38 PM ===
22:41:39|   Info| === Setup bootstrap logging started 6/22/2016 10:41:39 PM ===

A quick search soon lead me the following KB article

I was able to solve the problem by 
1)      Goto start then run and type Regedit and enter
2)      Goto following register entry 
	HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
3)      Delete the key RunOnce
After removing the entry my problem was solved.
