Can't seem to uninstall /update ivreg2

[Branon Xerxes]

I am having trouble with ivreg2 on my desktop. I have been trying to update/uninstall - but it won't. I get a bunch of seemingly contradictory responses:

. ssc install ivreg2
checking ivreg2 consistency and verifying not already installed...

the following files already exist and are different:
    c:\ado\plus\i\ivreg2.ado
    c:\ado\plus\i\ivreg2_p.ado

no files installed or copied
(no action taken)
r(602);

. ado uninstall ivreg2
package not found
r(111);

. which ivreg2, all

c:\ado\plus\i\ivreg2.ado
*! ivreg2 2.0.04  14Apr2004
*! authors cfb & mes
*! cloned from official ivreg version 5.0.9  19Dec2001


. ado uninstall ivreg2, from("c:/ado/plus/i")
package not found
r(111);

. ado uninstall ivreg2, from("c:/ado/plus/i/")
package not found
r(111);

I also ran

. adoupdate, update

but ivreg2 was not among the list to be updated/or considered already up to date.

You need (I think)

ssc inst ivreg2, replace

Whether adoupdate "knows" about a previous installation depends on how you did it. Copying files in by hand won't qualify.

That worked perfectly. Thanks!
