Can not install the package

Note that in case you get the following error:

InternetOpenUrl failed: 'An error occurred in the secure channel support'

Enter the command:

setInternet2(TRUE)

Alternatively, you may add to .Rprofile or Rprofile.site the following line:

options(download.file.method = "wininet")

Unable to move temporary installation

One common errors during the package installation is linked to the antivirus “real time file system protection”. The following will fix the problem:

trace(utils:::unpackPkgZip, edit=TRUE)

Edit line 140:

Sys.sleep(0.5)

to:

Sys.sleep(2)

Sys.getenv("TZ")

Error when building the dictionnary or configuration file

If you see this message (or similar error):

Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection

It is most likely because you have the form, dictionary or data set open in excel on your computer. Only a single session for that file is allowed in windos. If you close it and start over, the problem should be fixed.
