Run Vuser as a process
Run Vuser as a thread
Go through the below links and videos to better understand the difference between process and thread.

lr_continue_on_error function and its usage in Loadrunner

By using  Run-Tiime Settings:
Go to Vuser -> Run Time Settings -> Miscellaneous.
In Miscellaneous go to Error Handling and select Continue on Error. These setting applies to all the script including vuser_init and vuser_end.
By Using  lr_continue_on_error:
By using lr_continue_on_error function we can include a portion of the script instead of whole script. We need to enclose the requests that we are getting error in between lr_continue_on_error(1) and lr_continue_on_error(0)
lr_continue_on_error(1); web_url("Google", "URL=", "TargetFrame=", "TargetBrowser=Google ", "Resource=0", "RecContentType=text/html", "Snapshot=t1.inf", "Mode=HTML", LAST ); lr_continue_on_error(0); Controller Setting…

Yes, it true Loadrunner 11.52supportsWindows 8and Internet Explorer 10 but there are some limitations.
Windows 8 support is added in service pack 11.52. Loadrunner 11.52 supports Windows 8 x64 systems and Windows 7 x64. It does not support for Windows 8 x86 systems.
Restart is required after installing prerequisite Microsoft Visual C++ 2005 Redistributable Packages. After installing the prerequisites restart the machine before installing the setup.
On a Windows 8 64-bit operating system, VuGen cannot record when creating a script using Citrix and Web in multi-protocol mode. Recording is also not supported for the Oracle Web App 11i protocol. This is because the 64-bit version of Internet Explorer 10 is currently unsupported for these modes and protocols. Terminal Emulation (RTE)  scripts cannot be recorded or replayed on Windows 8. The TruClient Ajax - IE protocol is not supported for the Windows 8 operating system.
